by slowing it down.
To adjust the length of audio, do this:
1. Select the media file in the library that you want to adjust.
2. Click Adjust Length under the Adjust Audio section.
3. Decide whether you want to perform the adjustment on all the available
channels, or just one channel. See Selecting Channels for Editing for more
information on selecting channels.
4. If required, use range selection to select the portion of an audio file you want
to adjust the length of. If you don't select a range, the adjustment is applied
to the entire audio file. See Range Selection for more information on selecting
a range of an audio file.
5. To adjust the length of the audio, do one of the following:
Manually enter the New audio length in the field provided. Use this feature if
you want the audio to be an exact specified length.
Use the Stretch ratio slider if you want to increase/decrease the length by a
specific percentage.
Note: if required, you can use both the New audio length and Stretch ratio
features together to adjust the length of the audio.
6. Select the Keep pitch option to have CyberLink AudioDirector
maintain the pitch of the original audio, so that the adjusted result does
not sound sped up or slowed down.
Note: Keep pitch is only available if the change to the audio's length is between
0.5X and 2X.
